Design of supply and exhaust ventilation system
A favorable microclimate is one of the components of good health.
It is difficult to work and rest in a stuffy, unventilated room.
That is why today the issue of creating a high-quality ventilation system is given great importance.
Ventilation has become a mandatory element of cottages, offices, restaurants, shopping centers and educational institutions. This contributes to the increase in demand for such a service as ventilation system design, because the development of a competent project is the first step towards organizing effective air exchange.
Purpose of ventilation
The ventilation system performs a number of important functions, namely:
1
Ensures a constant comfortable temperature;
2
Removes dust, bacteria, and toxic substances from the air;
3
Maintains optimal humidity levels.
Design of supply and exhaust ventilation: features
In the process of designing supply and exhaust ventilation, it is necessary to make several important calculations – technical, thermal, energy, economic.
A mandatory condition is compliance with construction, sanitary and hygienic standards, fire safety rules, technological instructions, GOSTs and requirements for thermal protection of objects.
Design of a ventilation system includes the following stages:
1
Design of the general ventilation scheme;
2
Calculation of heat inflows;
3
Taking into account design requirements;
4
Feasibility study of the project;
5
Approval of the working project, making adjustments.
There is extensive regulatory documentation for heating, ventilation and air conditioning systems.
The main documents used in ventilation design:
1
СНиП 2.04.05-91 (2000) “Heating, ventilation and air conditioning”;
2
СНиП, regulating the type of buildings we need.
The flow rate and temperature of the supply air for ventilation are designed in accordance with the mandatory Appendix 17 to SNiP 2.04.05-91 (2000), which specifies the exact calculation method.
The required air exchange rate is taken from the “SNiP of the building”.
Thus, the ventilation scheme is derived from 3 main sources:
1
A set of ventilation schemes known for this building.
2
Regulatory documentation (SNiPs and other documents).
3
Specific customer requirements.
Calculation of heat inflows for ventilation design
1
External thermal loads occur outside the premises. They can be both positive and negative.
2
Internal thermal loads created by people and machines. They, on the contrary, are always positive.
Requirements for ventilation design
When designing ventilation, the following points must be taken into account:
1
Sanitary requirements;
2
Construction and architectural standards;
3
Fire safety regulations;
4
Operational requirements;
5
System reliability:
Feasibility study of the ventilation project
The feasibility study does not provide precise calculations for the ventilation system, but notes the following:
1
What ventilation scheme is chosen;
2
Key performance characteristics;
3
System configuration;
4
Equipment layout
5
Approximate cost of a ventilation system.
Working design of ventilation system
The working draft includes the following data:
1
Equipment composition.
2
Layout diagram.
3
Air duct and pipeline network plans.
